Scientists have finally cracked the code of the three dimensional structure of the human genome. This could lead to a better understanding of the function and structures of cellular DNA and how it folds at scales that dwarf the double helix, according to a report published Thursday. "By breaking the genome into millions of pieces, we created a spatial map showing how close different parts are to one another," said Nynke van Berkum, one of two primary authors of the study, which appears in the...

Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix. Present in the cells of all living organisms, DNA is composed of two intertwined strands and contains the genetic "blueprint" through which all living organisms develop and function. Individual strands consist of nucleotides, which include a base, a sugar and a phosphate moiety....

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems. "My lab has been trying to find a way to deliver genetic-based drugs into cells." said Reineke. Scientists worldwide are using information from the human genome project as an...

LONG BEACH, Calif., Sept. 10 /PRNewswire/ -- "Why free? I want to level the playing field. The only variable in this system is you. All I ask in return for using my system is for every user to share it with as many people as they can," said Bob Ainuu Afamasaga. "Millions of Europeans are losing their jobs...we must also keep the cost of all these measures in mind because, as I have already said several times, creating debt is no solution..." said European Council President Mirek...

New York University chemists have created three-dimensional DNA structures, a breakthrough bridging the molecular world to the world where we live. The work, reported in the latest issue of the journal Nature, also has a range of potential industrial and pharmaceutical applications, such as the creation of nanoelectronic components and the organization of drug receptor targets to enable illumination of their 3D structures. While scientists, including those involved in this study, have...

In the chilling science fiction movie Gattaca, Ethan Hawke stars as a man with "inferior genes" who assumes another's genetic identity to escape a dead-end future. The 1997 film illustrates the very real fear swirling around today's genome research "” fear that private genetic information could be used negatively against us. Last year, after a published paper found serious security holes in the way DNA data is made publicly available, health institutes in the United States and across...

Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns"”or "DNA origami""”on surfaces that are compatible with today's semiconductor manufacturing equipment. These precisely positioned DNA nanostructures, each no more than one one-thousandth the width of a human hair, can serve as scaffolds or miniature circuit boards for the precise assembly of...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
